At this moment I have my ovirt engi= n=3D e on our vmware environment which is fine for good backup and restore.=3D

I have 4 nodes running now all different in make and mo= d=3D el with local storage and it works but lacks performance a bit.

<= b=3D r>

But I can get my hands on some old dell=3DE2=3D80=3D99s R415 w= ith 96 G=3D b of ram and 2 quadcores and 6 x 1 Gb nic=3DE2=3D80=3D99s. They all come wi= th 2 x 1=3D 46 Gb 15000 rpm=3DE2=3D80=3D99s harddisks. This isn=3DE2=3D80=3D99t bad but= I will add m=3D ore RAM for starters. Also I would like to have some good redundant storage= f=3D or this too and the servers have limited space to add that.

<= /=3D div>

Hopefully others will also share there setups and expirience like = y=3D ou did.

Kind regards.

Hi,

HL ProLiant DL380, dual Xeon
120 GB RAID L1 for system
2 TB RAID L10 for VM disks
5 VMs, 3 Linux, 2 Windows
Total CPU load most of the time is low, high level of activity related to disk.
Host engine under KVM appliance on SuSE, can be easily moved, backed up, copied, experimented with, etc.

You'll have to use servers with more RAM and storage than main.
More then one NIC required if some of your VMs are on different subnets, e.g. 1 in internal zone and 2nd on DMZ.
For your setup 10 GB NICs + L3 Switch for ovirtmgmt.

BTW, I would suggest to have several separate hardware RAIDs unless you have SSD, otherwise limit of the disk system I/O will be a bottleneck. Consider SSD L1 RAID for heavy-loaded databases.

Please note many cheap SSDs do NOT work reliably with SAS controllers even in SATA mode.

For example, I supposed to use 2 x WD Green SSD configures as RAID L1 for OS.
It was possible to install system, yet under heavy load simulated with iozone disk system freeze, rendering OS unbootable.
Same crash was experienced with 512GB KingFast SSD connected to broadcom/AMCC SAS RAID Card.

performance issues. The VMs it is running are not high on IO (mostly small Linux servers). 3 node clusters: RAM: 32 GB per host CPU: 16 cores per host Storage: 5x 600GB in RAID5 (not ideal but I had to gain some storage space without purchasing extra disks) NIC: 6x Gbit VMs: less then 10 large Windows VMs (Windows 2016 server and Windows 10) For your setup (30 VMs) I would rather go with RAID10 SAS disks and at least a dual 10Gbit NIC dedicated to the gluster traffic only.

Thanks for sharing. Much appriciated.

I = b=3D elieve my setup would need 96 Gb off RAM in each host, and would need about= a=3D t least 3 Tb of storage. Probably 4 Tb would be beter if I want to work wit= h=3D snapshots. (Will be running mostly windows 2016 servers or windows 10 desk= t=3D ops with 6Gb off RAM and 100 Gb of disks)

I agree = t=3D hat a 10 Gb network for storage would be very beneficial.

Now If I can figure out how to set up a glusterfs on a 3 node cluste= r=3D in oVirt 4.2 just for the data storage. I =3DE2=3D80=3D98m golden to get s= tarted.=3D :-)

Kind regards.

I have 2 or 3 node clusters with following hardware (= all=3D with self-hosted engine) :

The VMs it is running are not high on IO (mostly= s=3D mall Linux servers).

3 node clusters:
RAM= :=3D 32 GB per host

Storage:= 5=3D x 600GB in RAID5 (not ideal but I had to gain some storage space without pu= r=3D chasing extra disks)
NIC: 6x Gbit

For your setup (30 VMs) I would rather go with RAID10 SAS disks and at lea= s=3D t a dual 10Gbit NIC dedicated to the gluster traffic only.

Hi all, Not sure if this is the place to be asking this but I was wondering which h= a=3D rdware you all are using and why in order for me to see what I would be nee= d=3D ing. I would like to set up a HA cluster consisting off 3 hosts to be able to ru= n=3D 30 vm=3DE2=3D80=3D99s. The engine, I can run on an other server. The hosts can be fitted with the = s=3D torage and share the space through glusterfs. I would think I will be needi= n=3D g at least 3 nic=3DE2=3D80=3D99s but would be able to install ovn. (Are 1gb= nic=3DE2=3D =3D80=3D99s sufficient ?) Any input you guys would like to share would be greatly appriciated.
